A trade union leader has revealed the shocking extent of deaths of 2022 World Cup workers in Qatar.

Qatar has come in for strong criticism over human rights and the treatment of migrant workers.

There are set to be eight stadiums in use for the tournament with organisers desperately trying to get them ready for four year's time.

It is unclear quite how many workers have died in preparing for the World Cup but Hans-Christian Gabrielsen, Leader of Norwegian Confederation of Trade Unions, has offered a frightening insight.

"If we were to hold a minute of silence for every estimated death of a migrant worker due to the constructions of the Qatar World Cup, the first 44 matches of the tournament would be played in silence," he said.
